Microsegmentation has long been a cornerstone of zero-trust security, but according to new Gartner research, the market is entering a new phase defined by complexity, automation, and rapid innovation.

Three Forces Are Reshaping Microsegmentation

Gartner® identifies three primary forces driving change:

AI Is Becoming a Key Differentiator

AI is transforming microsegmentation capabilities, enabling:

  • Anomaly detection across distributed environments
  • Dynamic policy adjustments in real time
  • Deeper insights into application and API behavior

But adoption is cautious.

Organizations still require human oversight, transparency, and strong safeguards to trust AI-driven decisions.

Cloud and Containers Are Increasing Complexity

Hybrid and multicloud environments have made segmentation significantly harder.

Challenges include:

  • Constantly changing workloads
  • Limited visibility into dependencies
  • Policy sprawl and misconfigurations

This is driving demand for:

  • Agentless microsegmentation
  • Real-time topology mapping
  • Deep cloud-native integrations

CPS/OT Environments Are Expanding the Attack Surface

As cyber-physical systems grow, so does the need for segmentation. However, most microsegmentation solutions:

  • Lack native CPS capabilities
  • Depend on third-party integrations
  • Struggle with fragmented and proprietary environments

This creates a major gap in security strategies.

The Trust Gap in Automation

Perhaps the most striking insight:

By 2030, 10% of organizations will have sufficient trust to run autonomous agents to segment their networks with no human oversight, up from less than 1% in 2026. This reflects both the promise and the hesitation surrounding AI-driven security.

What Organizations Should Do Next

Gartner recommends focusing on:

  • AI-driven risk scoring and compliance
  • Agentless enforcement across cloud and containers
  • Unified management with separate policies for IT and CPS
  • Improved visibility and policy automation

Final Takeaway

Microsegmentation is no longer just about segmentation, it’s about operationalizing zero trust at scale. And the organizations that succeed will be those that can balance:

  • Automation and control
  • Visibility and simplicity
  • Innovation and trust
